How to calculate the weight
weight of any tube can be calculated with the following formulas
| Imperial | Example |
|---|---|
| density (lbs/in³) | 0.284 lbs/in³ |
| x | |
| (OD² - (OD - 2xT)²) | (3.0 in² - (3.0 in - 2x0.022 in)²) |
| x | |
| Length | 12in |
| x | |
| π/4 | |
| = | |
| weight | 0.702 lbs |
| Metric | Example |
|---|---|
| density (g/cm³) | 7.85g/cm³ |
| x | |
| (OD² - (OD - 2xT)²) | (50.0 mm² - (50.0 mm - 2x1.0 mm)²) |
